Problem Analysis

Lena has thought of a certain number, added the number 5 to the right of it, and then added 7 to the result. The final result is 72. We need to determine the number that Lena initially thought of.

Solution

Let's break down the problem step by step:

1. Lena thought of a number. 2. She added the number 5 to the right of it. 3. She added 7 to the result. 4. The final result is 72.

To find the number Lena initially thought of, we need to reverse the steps:

1. Subtract 7 from 72 to get the intermediate result. 2. Subtract 5 from the intermediate result to get the final answer.

Let's calculate it:

1. Intermediate result = 72 - 7 = 65. 2. Final answer = 65 - 5 = 60.

Therefore, the number Lena initially thought of is 60.

Conclusion

Lena initially thought of the number 60.
